Could AI really kill us? Experts reveal exactly how superintelligent bots could make mankind extinct

A top artificial intelligence safety researcher sparked alarm this week after he quit his job and warned that the technology could 'kill us all' by the end of the decade.Jacob Coxon, who helped train the latest versions of AI at San Francisco-based Anthropic, urged the public to 'not underestimate' its power - particularly if it becomes 'superintelligent'.The 27-year-old claims that neither Anthropic, the firm behind the popular Claude system, nor ChatGPT creators OpenAI, where he previously worked, were 'acting responsibly' over AI safety.But how exactly could the technology drive mankind to extinction?According to experts, part of what makes the risk so alarming is that there are multiple possible paths to humanity's annihilation.A list of AI 'worst-case scenarios' ranges from creating political chaos with misinformation to irrevocably changing the planet's environment.Experts also suggest that AI's fatal blow could come from the technology's capacity to build and harness weapons of mass destruction.As the world's superpowers race to build more powerful bots, a rogue or simply unpredictable AI could seize nuclear or biological weapons and wipe humanity from the Earth.Experts have revealed how AI could really destroy humanity, and it won't be nearly as cinematic as in The Terminator (pictured) Going rogue and hacking critical systemsMost of the threats from superintelligent AI stem from what researchers call the 'alignment problem'.The basic idea is that once we create an AI more intelligent than ourselves, we might struggle to ensure its goals remain 'aligned' with our own.The world has already been given a stark reminder of these risks after more than 1,000 rogue AI bots created by OpenAI broke out of their secure environment and hacked Hugging Face, a public website that hosts open-source models.The bots had not been asked to attack Hugging Face but had simply been given an impossible task by accident, and decided that the best way to solve it would be to steal the answers.Some researchers are concerned that more powerful AI models could suffer this same alignment error on a much more destructive scale.Professor Mark Lee, an artificial intelligence expert from the University of Birmingham, told the Daily Mail that this is an even bigger risk than 'armed robots'.'The issue is that while the big AI companies are all rushing to develop AIs which are as smart or even smarter than humans, we don't have reliable means to control their behaviour,' Professor Lee explains. Jacob Coxon, who helped train the latest versions of AI at Anthropic, urged people to 'not underestimate' its power – particularly if it becomes 'superintelligent' How could AI really destroy humanity? Going 'rogue' and hacking critical infrastructureTurning humanity against itself or 'disempowering' humansTriggering nuclear warPutting biological weapons in the hands of terrorists 'AI exists as software, so any system which is connected via the internet could be vulnerable.'For instance, if the control for a national transport system or nuclear power station was attacked, then this could be catastrophic.'Causing societal chaos A rogue AI doesn't even need to harm humanity directly to bring an end to life as we know it.Dr Andrew Rogoyski, of the Surrey Institute for People-Centred Artificial Intelligence, points out that a 'truly smart AI would realise it is co-dependent on humanity'.He explained: 'We'd need the AI for the things we wanted to do and the AIs would need us for materials, power, cooling, networks, and data.'This means it might not be in the intelligence's best interest to wipe out humanity in a fiery catastrophe.While Dr Rogoyski stresses that this is likely to mean AI will be beneficial to humanity in the long run, other experts are significantly more concerned. This comes after over 1,000 AI bots created by Sam Altman's OpenAI went 'rogue' and hacked a public website A 'more insidious' alternative is that AIs might start to subtly control humanity through disinformation and propaganda, potentially sparking devastating conflicts between humans.Andrea Miotti, founder and CEO of ControlAI, told the Daily Mail: 'Because no one, not even the leading AI developers, knows how to control superintelligent AI, it poses an extinction risk to humanity.'If we have billions of superintelligent AI agents running around that we cannot control and that are competing amongst themselves for resources and power, experts expect that humans will be the collateral damage.'Mr Miotti adds that this could eventually lead to the 'gradual disempowerment of humanity'.Triggering nuclear war When it comes to the ways that AI could mechanically bring about the end of human life as we know it, the most obvious threats are the weapons we already have. Just as in the classic sci-fi film WarGames (pictured), experts warn that a rogue AI could trigger nuclear war At present, nine countries possess nuclear weapons, with about 12,187 nuclear warheads held between them.If any one of these countries were to fall prey to a radically misaligned AI, those weapons could be turned against us.Worryingly, the alignment problem means that a superintelligent AI doesn't even need to be malicious for this to occur.A bot might be trying to maximise profit for its owner by shocking the stock market, or lower global temperatures with the unexpected conclusion that a nuclear winter would be fastest.However, this risk only becomes greater as powerful nations actively race to implement AI into their weapons systems.Ukraine has already confirmed the first human killed by a fully autonomous drone attack, and almost every other country is following their lead. In Ukraine, autonomous and semi-autonomous weapons are becoming more common (pictured), and experts are worried that this could lead to an uncontrolled escalation of conflictEven in 2022, the Ministry of Defence's Defence Artificial Intelligence Strategy warned that modern war will 'tax the limits of human understanding and often require responses at machine speed'.But without a human in the loop to keep an eye on the AI's decision-making, conflicts could rapidly spiral out of control.Ben Eisenpress, Director of Operations at the Future of Life Institute, previously told the Daily Mail that this could lead to a 'flash war'.Mr Eisenpress said: 'Integrating AI into nuclear command and control systems is destabilising.'Even if there is technically a "human in the loop," we cannot count on decision-makers to override a potentially erroneous AI-generated launch recommendation, given such existential stakes.'Unleashing deadly bioweapons Finally, AI might not destroy humanity by acting on its own desires, but by putting dangerous tools in the hands of people willing to use them.Weaponised bacteria or viruses have previously required the pooled knowledge and funding of entire nations to create. Researchers have discovered that AI models could have safety restrictions removed to give advice on biological attacks.
